Geoff, I’m not sure it needs a complete post, I’ll try to answer it shortly here. From AC19 we use font types value lists from the “Archicad_library_master”. If you open it from the editor, you’ll see how we add value lists to all the loaded library parts. You can do the same, add your own “master” libpart to your package, and create value list for your own libparts. This master libpart should be under the “Library Master” subtype. Maybe later we can describe it with more details, for now, feel free to ask more questions if needed.
